Well, they will need to do something.
TNG is very dear to my heart, but on a big screen the quality falls apart on DVD and it's a little bit nasty. Some shots are better than others, of course. There's a scene of a K'Vort firing (they used it several times, I'm pretty sure it was in Yesterday's Enterprise also) where you can see a video distortion line pass over the ship as it moves.
The show (more than) deserves the TOS remastered treatment.
